How much does the Oscar EDM ZX 550 cost?
Price estimate
We do not have a price for the Oscar EDM ZX 550 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Oscar EDM ZX 550 is a die-sinker EDM with an 800 x 450 mm (31.5 x 17.7 in) table, 500 mm (19.7 in) of X travel, 400 mm (15.7 in) of Y and a Z-axis servo travel of 350 mm (13.8 in). Oscar EDM's table for it is a plain one: it gives the mechanical and generator figures and has no control, display or axis-count row.
That gap is the first thing to resolve. The NX 550 has the same 800 x 450 mm table and the same 1,950 kg (4,299 lb) machine weight, and its listing names a Windows 10 control on an industrial i3 (or above) 64-bit CPU. Nothing equivalent is stated for the ZX 550, so get the control specification from Oscar EDM before comparing the two.
The mechanical side is clear. The chuck sits 135 - 485 mm (5.3 - 19.1 in) above the table, a span that equals the 350 mm servo stroke, so the two rows describe one continuous Z movement. With 135 mm as the closest approach, a thin plate burned with a short electrode needs a spacer underneath; work held on a taller block is unaffected. Dielectric fills to 260 mm (10.2 in) at most.
Capacity is generous for a machine of 1,950 kg. The table takes 1,350 kg (2,976 lb), more than two-thirds of the machine's own weight, in sizes up to 1100 x 630 mm (43.3 x 24.8 in). Electrodes can weigh 220 kg (485 lb). Against that, the 60 A maximum working current and 6 kVA power consumption point to detail work and moderate burn areas, not to roughing big faces.
The dielectric system is a 520 L tank with 3 filter elements rated at 20 μm, and the generator weighs 320 kg (705 lb).

Strengths & Limitations
Strengths
- Carries workpieces up to 1,350 kg (2,976 lb) on a machine that weighs 1,950 kg (4,299 lb)
- Chuck-to-table range of 135 - 485 mm (5.3 - 19.1 in) lines up with the 350 mm (13.8 in) Z servo travel
- Maximum workpiece of 1100 x 630 mm (43.3 x 24.8 in) exceeds the 800 x 450 mm (31.5 x 17.7 in) table
- Electrodes up to 220 kg (485 lb)
- Low service demand: 6 kVA power consumption and a 520 L dielectric tank
Limitations
- No control, display or axis count appears in the listing, so the control specification has to be requested
- 60 A maximum working current makes large-area roughing slow
- No more than 485 mm (19.1 in) between chuck and table for workpiece, electrode and holder together
- Dielectric fill height stops at 260 mm (10.2 in)

Frequently Asked Questions
01
The listing for the ZX 550 does not state one. Its rows cover travels, table, weights, generator and dielectric only. The NX 550, which shares the 800 x 450 mm (31.5 x 17.7 in) table and 1,950 kg (4,299 lb) machine weight, is listed with a Windows 10 control on an industrial i3 (or above) 64-bit CPU. Ask Oscar EDM what the ZX 550 is supplied with.
02
Between 135 and 485 mm (5.3 - 19.1 in) from chuck to table, covered by 350 mm (13.8 in) of Z-axis servo travel. The workpiece, the electrode and its holder have to fit within 485 mm, and the area being burned must stay under the 260 mm (10.2 in) maximum dielectric level.
03
Up to 1100 x 630 mm (43.3 x 24.8 in) and 1,350 kg (2,976 lb), on an 800 x 450 mm (31.5 x 17.7 in) table. X and Y travels are 500 mm (19.7 in) and 400 mm (15.7 in), so on a full-size block the head reaches only the central part without moving the workpiece.
04
Maximum working current is 60 A and power consumption is 6 kVA. The generator weighs 320 kg (705 lb). Those figures suit finishing and moderate electrode areas; shops that rough large cavity faces every day will want more current than this.
